Install Virtualbox guest additions on Fedora 21 XFCE

Installing via the normal route didn’t work and meant I couldn’t easily resize the screen. Doing the below allowed me to use the resize easily.

1. Install rpmfusion on fedora
2. run `sudo yum install akmod-VirtualBox VirtualBox-guest`
3. run `cd /usr/src/akmods`
4. run `sudo rpm -ivh VirtualBox-*.rpm`

Once this was installed, rebooting will give you access to shared folders and fullscreen mode

Found the fix on the fedora forums for fedora 19
